The present invention relates to novel humanized, chimeric and murine antibodies that have binding specificity for the human CC chemokine ligand 20 (CCL20). The present invention further relates to heavy chains and light chains of said antibodies. The invention also relates to isolated nucleic acids, recombinant vectors and host cells that comprise a sequence which encodes a heavy chain and/or a light chain of said antibodies, and to a method of preparing said antibodies. The anti-CCL20 antibodies of the invention can be used in therapeutic applications to treat, for example, inflammatory and autoimmune disorders and cancer.

A Compound represented by the following general formula (1): wherein R, R, Rand Reach independently represent hydrogen, etc.; Rrepresents optionally substituted phenyl, etc.; Rrepresents optionally substituted C6-10 aryl, etc.; and Zand Zeach independently represent hydrogen or salts thereof or hydrates of the foregoing.

A Compound represented by the following general formula (1), salts thereof or hydrates of the foregoing is a novel compound useful for treatment and/or prevention of diseases associated with thrombus formation, and which is safer with suitable physicochemical stability. [wherein R, R, Rand Reach independently represent hydrogen, etc.; Rrepresents optionally substituted phenyl, etc.; Rrepresents optionally substituted C6-10 aryl, etc.; and Zand Zeach independently represent hydrogen]

The present invention provides a preventive or therapeutic agent of a new type for diabetes mellitus and diabetic complications on the basis of an adenosine A2 receptor antagonist action. A purine compound represented by the formula (I), its pharmacologically acceptable salt or hydrates thereof has an adenosine A2 receptor antagonistic action and is useful for prevention or therapy of diabetes mellitus and diabetic complications. In addition, adenosine A2 receptor antagonists having different structures from those of the compounds described above, for example KW6002, are also effective for prevention or therapy of diabetes mellitus and diabetic complications. In the formula, W is &#x2014;CHCH&#x2014;, or &#x2014;CH&#x2550;CH&#x2014; or &#x2014;C&#x2261;C&#x2014;; Ris:(in the formula, X is hydrogen atom, hydroxyl group, a lower alkyl group, a lower alkoxy group, etc.; and Rand Rare the same as or different from each other and each represents hydrogen atom, a lower alkyl group, a cycloalkyl group, etc.) and the like; Ris an amino group, etc. which maybe substituted with a lower alkyl group, etc.; Ris a cycloalkyl group, an optionally substituted aryl group, etc.; and Ris a lower alkyl group etc.

Purine derivatives and adenosine A2 receptor antagonists serving as preventives/remedies for diabetes

The present invention provides a preventive or therapeutic agent for diabetes mellitus and diabetic complications, which is a new type based on an adenosine A2 receptor antagonist action. That is, it provides a novel condensed imidazole compound which has an adenosine A2 receptor antagonist action, is effective for preventing or treating diabetes mellitus and diabetic complications, and is represented by the formula (I);(wherein Rrepresents e.g. an amino group which may be substituted with an alkyl group; Rrepresents e.g. hydrogen atom, an alkyl group, a cycloalkyl group or an alkyl group, alkenyl group or alkynyl group which may be substituted with hydrox etc.; Rrepresents e.g. an optionally substituted alkyl group, alkenyl group, alkynyl group, aryl group, heteroaryl group, pyridinone group, pyrimidinone group or piperadinone group; Ar represents e.g. an optionally substituted aryl or heteroaryl group; and Q and W are the same as or different from each other and each represents N or CH), a pharmacologically acceptable salt or hydrates thereof.
